Fuck them, along their shit ass product, and customer service.
So now thats out of the way. I bought (2) suppressors from them, one for my AR (Kestrel) one for my 15/22 (Guardian SS). Stamps came in 2 months ago, so I go down to my dealers land to shoot them and try out some other class 3 goodies. Well first try the .22 on my 15/22 and with CCI standard velocity, the thing is stupid quite, Im impressed. Next I throw the Kestrel on my SBR with Innovatives Arms W.A.R. Upper (which is awesome!!). Fire the gun, fuck loud as hell, I mean my ears a bleeding loud (was wearing plugs, so not really, but you get the idea), shoots a massive fireball out the end (which my dealer got on video), and it wont cycle with the W.A.R. receiver on "suppressed". So we run a couple rounds through it thinking, things might change, nope, nothing.
Well, Im thinking now its just b/c it's on SBR its loud like that. Then next thing I know my dealer comes out with a Liberty, AAC, and an Innovative Arms Grunt Mini. We run them all on my SBR and what do you know it actually sounds suppressed and two of the three (Liberty was a little to loud not to wear plugs) were hearing safe, IMO for my ears, along with my dealer and buddy who were shooting it ears (and in before I get told about dB and the human ear and hearing loss), but the AAC and the Grunt Mini, worked awesome, sounded great, no massive fireball, and it cycled my BCG with the upper on "suppressed".
My dealer calls HTA, tells them whats going on, about the sound and fireball. They say weird and the fireball throughs up some red flags, so we send it back. About a month goes by and nothing, dont hear a word. Mined you Ive called them daily and sent emails, not a word back. I get my dealer involved and they give him the run around, for a couple weeks. Finally they get back to him, say the owner went and shot it, and tell us everything is fine and well within the specs, thanks for buying our can, and for buying it we cleaned it for free for you.
My dealer being a stand up guy, buys the can back from me and is giving me dealer pricing on an AAC SDN-6, really I couldnt ask anything more from my dealer, but fuck HTA.
